IIRC, dotLRN eventually is supposed to move a lot of the community/class/portal management based functionality back into OpenACS 4.7's subsites, etc.
There is a lot of interest in dotWRK. Would it be wise to take the above into account and share planning and/or resources even at this stage of development? I could see dotWRK reworking the acs_subsites, while dotLRN finishes reworking portal, etc. In the end OpenACS 4.7 gets out the door faster, as well as dotLRN 2 and dotWRK.
If it isn't already obvious, I'm still interested in dotWRK, but I would prefer that it was based on what I see as the fundamentally better idea of dotLRN 2.
